  • FunctionHigh affinity receptor for N-formyl-methionyl peptides, which are powerful neutrophils chemotactic factors. Binding of FMLP to the receptor causes activation of neutrophils. This response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system.
  • Tissue specificityNeutrophils.
  • Sequence similaritiesBelongs to the G-protein coupled receptor 1 family.
  • Post-translational
    Phosphorylated; which is necessary for desensitization.
  • Cellular localizationCell membrane.

Thank you for your reply.

I have confirmed with the laboratory that we have not tested the antibody for cross-reactivity with FPR2. However, I compared the sequence of the peptide used to generate ab113531 to the corresponding region of FPR2...

Thank you for contacting Abcam regarding ab113531.

Regarding the molecular weight of the FPR1 protein, the predicted molecular weight is indeed 38kDa, however this protein is also subject to several posttranslational modifications, including...
